Sixteenth-Brick Converters Squeeze Into Low-Profile Apps

The PKU-C series isolated DC/DC power converters come in an industry-standard sixteenth-brick form factor and deliver an output current up to 20A, or an output power equivalent to 100W. Addressing mid-range IT and communications power applications that are migrating from multiple-output power modules to fully regulated intermediate bus converters, the DC/DC modules fit into a height profile of less than 9 mm. Designed to operate with a 36V to 75V input voltage range, the PKU-C series is primarily designed for applications that are powered by a centralized 48V bus. However, due to its efficient and flexible power performance, the series is also suitable for a wide range of applications including those in industrial, process control, and automation. Two models are available, the 12V PKU4104C and 5V PKU4105C. As they are isolated and feature floating outputs, the two modules can be combined to power the 12V and 5V rails in a disk-drive-array application requiring higher power than 100W. Price for PKU-C series components in OEM quantities is $24.50 each. ERICSSON INC., Plano, TX. (972) 583-6910/-5254.
